If you white balance to an object that you consider your "perfect white," there is no reason I can think of that should cause that to change during the filming of that shot, so long as you don't change the settings, or the lighting after white balancing. Most people use a white balance card, or a sheet of white paper to balance, but you could zoom in on the snow, or a white jacket, if that is what you consider a perfect white for your shot.
Let me emphasize that you cannot white balance, then change the settings, and expect to have the same white balance that you started with.
